1: Only the value specified against the axis 1 is valid for the logic selection of manual pulse generator input (b8).
2: When a servo amplifier is used and HPR is being executed, the setting is ignored. For the input logic specification
of the servo amplifier, refer to the instruction manual of the servo amplifier to be used. [CiA402 mode]
: Refer to Section 5.2 "List of parameters" for the information on detail settings.
[2] Precautions on parameter setting
(1) The external I/O signal logic switching parameters are validated when the
PLC READY signal [Y0] is turned OFF to ON. (The logic is negative right
after power-on.)
(2) If the logic of each signal is set erroneously, the operation may not be carried
out correctly.
Before setting, check the specifications of the equipment to be used.
(3) When the same external input signal is set to use to the multiple axes in
"[Pr.80] External input signal selection" or "[Pr.95] External command signal
selection", "Input signal logic selection" of those axes should be the same.
Otherwise, the error "Input signal logic selection setting error" (error code:
938) occurs when the PLC READY signal [Y0] is turned ON, and the READY
signal [X0] will not be turned ON.
